Admittedly didn't test the street. I thought about it, and on paper it's a better bike for my needs. But in my heart I wanted a speed, so bought one instead 
I upgraded from an F800S, which only has 82hp but a relatively flat torque curve - I really wanted a similar style of power profile, and I believe the street's a bit more peaky. I've only had it since January, so only now getting to see what it's like on dry roads, but think it's fantastic. Handling and ride position is spot on for B road adventures and the engine is great.
Downsides? It's a little heavy I guess, think it's 215 wet. The full beam lights are a bit pants, and like most naked bikes, the mirrors are occasionally useless. These are all small usability things that don't really matter when you're buying one though. I do question the value of the R - yes, you get lighter wheels and better suspension, but not sure if it's worth it on the road. They do look great though.
